PUMP.

SPECIFICATION forming part of Letters Patent No. 339,005, dated March 30, 1886.

Application (iled October 5, 1885. Serial No. 170,006. (No model.)

To all whom, t may concern:

Be it known that I, ELIJAH NEFF, a citizen of the United States, residing at Rochester, in the county of Fulton and State of Indiana, haveinvented certai n new and useful Improvements in Pumps, of which the following is a speciiication, reference being had therein to the accompanying drawings.

My invention relates to improvements in pumps, and is designed to produce a pump that will carry the iluid to any desired height, giving a constant and steady iiow,combining the lift and force impulses.

rIhe improvement consists, essentially, in providing ameans of lubricating the bearings, air-chambers for regulating the ilow, and a means whereby the pump mechanism is centrally located on the pipe.

In the drawings, Figure l represents a vertical section of the pump, and Fig. 2 a crosssection through the pump-cylinder.

The cylinder, as a whole,consists of a barrel, A, carrying heads B, each with a central opening, to which connect the inlet-pipe C to the lower head andthe outlet-pipe D to the upper head. Between the heads and the barrel are diaphragms F, each provided with a perforation, F. rIhe barrel, heads, and interposed diaphragrns are held in conjunction by collars Gr.

W'ithin the barrel, between the diaphragms, is a frame, II, preferably quadrantal in form. This frame coincides with the perforations F, and is divided into two chambers by a lateral diaphragm, I. The lower chamber is provided with outlet -valves K and the upper chamber with inlet-pipes L. The inlet-pipe C is capped by a valve, llI.

To the pump-rod N, which passes centrally through the upper diaphragm and is stepped` in a central boss, O, in the lower diaphragm, is secured a radial plate, I), which with its packing Iits snugly between the frame II and the wall of the cylinder and between the diaphragms E. The rod N passes upward centrally through the outlet-pipe D and a lubricator-cup, It, having suitable packing, S, and is provided near its upper end with apinion, T.

On a hollow standard, U, through which the pipe I) extends, and is secured and supported at its upper end, is a U-shaped or branched pipe, V, with a continuation, XV, forming the spout of the pump. The pipe V has connection to the outlet-pi pe D. On each of the arms o1" the pi pe'Vis supported a chamber, X, form ing air-chambers, being above the outlet or spout. The upper ends of the chambers X are closed, and have on top sockets Y, for the transverse shaft Z, on which is a segment-gear, A', meshing with the pinion T on the rod N, the upper end of which rod has a guiding-bearing consisting ofan arm, B, projecting from one ot thechambers X. Surmounting the said chambers, and inclosing the ends of the shaftZ and its bearings, are extended caps C, connected bya piece, D. On top these caps rest the oil or lubricator cups E', feeding the lubricant to the bearings of the said shaft Z. n

Space and material are economized by ut1lizing the airchambers as supports for the operating-shaft and its lubricators. The eylinder is also strengthened and material economized by forming it in such a manner as to permit all the connections being central.

The opera-tion is so simple as to need but a brief notice. rIhe rod is given by means of the gear a vibrating movement, covering nearly threequarters of a revolution at each stroke. As the plate I nieves within the cylinder', it causes the Huid to flow into the lower chainber in the frame I-I and out the valve from which it is receding into the barrel. On the return of the plate the valve in the lower chamber closes and that in the upper chamber opens, permitting the entrance of, the iuid therein. The chamber having been filled, .the ilnid passes through the opening in the upper diaphragm into and up the outletpipe. The iiuid constantly flows out oi' one chamber and into the other. According to the rapidity with which the pump is worked, the duid will encroach more or less into the air-chambers- The air therein, acting as a cushiomwillcause the fluid to steadily ilow from the spout.

The pump is equally applicable to deep or shallow wells, in the former ease some powersuch as steunt-being applied.

I claim- 1. Combined with a vibrating piston consisting of a radial plate on a pump-rod, a cylinder consisting of a barrel, asector-frame divided into two chambers provided with valves and contained in said barrel, perforated dia- IOO tive movement, a radial plate on said rod, form- 1 5 ing a piston, an outletpipe surrounding said rod, abranehed pipe on top of said outlet, airohambers on said branched pipe, a rock-shaft resting on said chambers and connected to said rod, and caps with oil-oups surmounting said chambers, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
